I have just been puzzling over the 'pink highlight' problem on several raws I recently shot (not HDR), all of which have blown highlights caused by a  camera operator silly error :)  I recently created a custom style for my camera and I thought that was something to do with the problem, so I'm glad it's a known characteristic for which a solution is available - don't over-expose!

I also noticed that Highlight Reconstruction was switched on on these raws and I hadn't done it as I like to start from a blank canvas, so switched it off. Reading the trail of replies however, it seems the only way to fix/reduce the pink problem is to use
Highlight Reconstruction - so I'm now wondering if DT automatically switches Highlight Reconstruction on if it detects blown highlights; does anyone know?

Thanks

A 'pink/magenta' cast is normally an indicator of overexposure (on a single raw file) ... the red and blue pixels have been flooded on the sensor. Is it possible that one of your HDR exposures is simply putting data out-of-normal range?

Hi,

This is my first time using a mailing list so please bear with me if this is not the correct way to ask a question. I sent this two weeks ago, but have not received any replies.

I have had an issue for some time in darktable with HDRs having a pink/magenta tint. This issue seems to have appeared and been fixed in the past. For example, user "bva" reports the same problem here: https://darktable-devel.narkive.com/vBQahOFL/hdr-pink-colors
Pretty much all of the conditions are the same for me; CR2 raw files, pink tint, heavy mazing.

Thank you,
